Avril Lavigne Rocks Her Album Release Party in the Big Apple

An unlikely group, couple Avril Lavigne and Brody Jenner and new lovebirds Kris Humphries and Kim Kardashian, were hanging at at SL Lounge in NYC last night for Avril's album release party for her new album Goodbye Lullaby. Unknown to some, Kim is the step-sister of Brody. Brody's dad, Bruce Jenner, and Kim's mom, Kris Jenner, are happily married!

Avril dished to MTV News about working with producer Max Martin:  “I flew out to Sweden for a couple weeks, sat down, played him my record, got to know each other, wrote some songs together, and then I was out,” she says. “It switched it up for me. It was a new creative space, a new relationship, and we got a lot done. He’s very talented.”

This is Avril's first album in 4 years! We've  missed Avril and from what we've heard off the album so far, we're loving it! Such a fun, upbeat album!
